Some of the rules of the school were curious. Until they were twelve years old the boys had to keep their hair cut short, after that they were allowed to wear a pigtail, but could powder their hair only on Sundays and Saints' Days. Each boy had a separate room which was much like a cell, containing a hard bed with only a rug for covering. The boys had to stay in school for six years, and they were never allowed to leave on any pretense whatever. During the long vacation which lasted from September fifteenth to November second they had only one lesson a day and had plenty of time for outdoor sports. Everything possible was done to fire their ardor for military life. They were encouraged to read the lives of great men, especially Plutarch's "Lives," and those historical plays which deal with great French scenes. History and geography were the chief studies, and after those two, mathematics. In all of these branches Bonaparte took great delight. Singularly enough the school, although designed to train boys for warriors, was entirely under the charge of an order of Friars. Neither teachers nor boys could help but admit Napoleon's great strength of character. When the Abbe in charge organized the school into companies of cadets the command of one company was given to this boy. He ruled those under him with a rod of iron, and finally the boys who were the commanders of the other companies decided to hold a court-martial. Bonaparte was brought before them and charged with being unworthy to command his schoolfellows because he disdained them and had no real regard for them. Arguments attacking him were made by various boys, but when it came to Napoleon's turn to defend himself he refused, on the ground that whether he were commander or not made little difference to him. The court-martial thereupon decided to degrade him from his rank and a formal sentence was read aloud to him. He seemed very little concerned, and took his place with the other privates without any show of ill feeling. For almost the first time the boys felt a sort of affection for him because he bore his humiliation so well. Unlike most boys he really seemed to care very little whether he was popular or not; all he asked was a chance to learn the art of warfare. He was happiest when he was left alone to study history. Plutarch's "Lives" was his favorite book, and his favorite nation among the ancient peoples was that of Sparta, because he admired the Spartans' stern sense of heroism and hoped to copy them. That was the reason Monsieur Pichegru had given him the nickname of "The Spartan," and the name stuck to him for years.
